[0085] The same length of the self-adhesive skirting obtained in Example 1, the self-adhesive skirting obtained in Example 2, the self-adhesive skirting obtained in Example 3, the self-adhesive skirting obtained in Example 4, the self-adhesive skirting obtained in Example 5, the self-adhesive skirting obtained in Example 6, the self-adhesive skirting obtained in Example 7, the self-adhesive skirting obtained in Example 8, the self-adhesive skirting obtained in Example 9, the self-adhesive skirting obtained in Example 10, the self-adhesive skirting obtained in Example 11, the self-adhesive skirting obtained in Example 12, the self-adhesive skirting obtained in Example 13, the self-adhesive skirting obtained in Example 14, the self-adhesive skirting obtained in Example 15 and the self-adhesive skirting obtained in Example 16 were used in the operation, and the tensile strength, elongation at break, wear resistance, moisture penetration, adhesion and environmental protection were tested to obtain the following table:

[0086] Table 1 Performance test table of self-adhesive skirting board

[0087]

[0088]

[0089] As can be seen from Table 1, 80% XPS particles, 20% CO2 (Examples 1-4) are compared with 75% XPS particles, 25% CO2 (Examples 5-8), 70% XPS particles, 30% CO2 (Examples 9-12), and 65% XPS particles, 35% CO2 (Examples 13-16), respectively. The use of a higher proportion of XPS particles generally provides higher tensile strength and adhesion;

[0090] The PET films (Examples 3, 4, 7, 8, 11, 12, 15, and 16) generally performed better than the PVC films (Examples 1, 2, 5, 6, 9, 10, 13, and 14) in terms of wear resistance, which may be due to the structure of the PET material being more able to withstand mechanical loads;

[0091] At the same ratio, the thickness of the film (0.5mm vs 0.8mm), although increasing the thickness usually provides a better overall structure, the wear resistance is not necessarily significantly improved, showing a diminishing marginal utility of performance improvement;

[0092] Example 7 was determined to be the optimal ratio, and the rigid foam ratio and the outer film type often have a positive impact on performance indicators such as tensile strength, wear resistance, and adhesion. In order to further optimize the performance, while maintaining the XPS particle ratio, PET film was selected as the outer layer material, and further experimental verification can be carried out between different thicknesses of the bottom layer IXPE.

[0093] Embodiment 17

[0094] This embodiment provides a technical solution: a self-adhesive skirting board, comprising an outer layer, a middle layer and a bottom layer, wherein the hard foam ratio of the middle layer is: 75% XPS particles, 25% CO2, the outer layer film type is: PET outer layer, thickness 0.5mm, and the bottom layer IXPE thickness is 5mm.

[0095] Embodiment 18

[0096] This embodiment provides a technical solution: a self-adhesive skirting board, comprising an outer layer, a middle layer and a bottom layer, wherein the hard foam ratio of the middle layer is: 75% XPS particles, 25% CO2, the outer layer film type is: PET outer layer, thickness 0.5mm, and the bottom layer IXPE thickness is 7mm.

[0097] The self-adhesive skirting obtained in the seventh embodiment, the seventeenth embodiment and the eighteenth embodiment of the same length were used in the operation, and the tensile strength, elongation at break, wear resistance, water penetration, adhesion and environmental protection were tested to obtain the following table:

[0098] Table 2 Performance test table of self-adhesive skirting board

[0099]

[0100]

[0101] It can be seen from Table 2 that by comparing the performance of a self-adhesive skirting prepared in Example 7, Example 17, and Example 18, Example 17 can be considered as the optimal embodiment, especially in terms of tensile strength and moisture permeability, it has significant advantages. It can be seen that with the increase of IXPE thickness, key performance indicators such as tensile strength and adhesion are generally improved, while the moisture permeability decreases, indicating that the thickness has a positive impact in many aspects, but the appropriate IXPE thickness should be maintained to ensure good environmental protection and wear resistance. If the data is too little, more groups can be made.

[0102] The above are only preferred embodiments of the present invention, which are only illustrative and not restrictive. Those skilled in the art understand that many changes, modifications, and even equivalences may be made to the present invention within the spirit and scope defined by the claims, but all of them will fall within the scope of protection of the present invention.
